Efficient way of finding the rank of the constraint matrix

I'm using Gurobi via the python module gurobipy. Suppose I've built a model by adding constraints one by one. After that, I would like to determine whether my constraint matrix is injective, or, equivalently, whether the rank of the constraint matrix equals the number of variables. I probably could export the constraint matrix to a numpy matrix and use numpy functionality, however, I wonder if there is a way to do this with Gurobi directly, which is maybe more efficient than exporting the matrix to numpy.

Thanks a lot in advance for your ideas and hints!
